#IBM WEBSPHERE SDK JAVA 7 DOWNLOAD DRIVER#
How does the WebSphere decide which TLS protocol the JDBC driver should use?Īnswer: WebSphere and the JDBC driver both use the underlying Java Virtual Machine (JVM) to create TLS connections. What JDBC data source driver custom properties need to be configured in WebSphere?Īnswer: This depends on type of database and driver used for connection. Server: Database Server – Example: (IBM DB2, MS SQL server, Oracle) etc. These answers are general, and database specific configurations are discussed later on in this blog.Ĭlient: WebSphere Application Server - JDBC provider/ Data Source driver - Where a JDBC Provider is configured (using a JDBC Driver jar file), under which a Data Source is defined, to be used by an application running on the WAS server to establish connections to a Database Server. These are common questions we receive when talking to customers about setting up TLS connections to backend databases. WebSphere Secure connection Data Source architecture flow: TLSv1.2 and TLSv1.3 are the new industry standard protocols that are considered secure. SSL - TLSv1 and TLSv1.1 Protocol are deprecated and considered insecure. For example, with RSA, the client uses the server's public key, obtained from the public key certificate, to encrypt the secret key information. The client and server exchange information that allows them to agree on the same secret key. A cipher suite is a set of cryptographic algorithms and key sizes to encrypt data.Īuthenticating the server allows the client to be sure that the server represents the entity that the client believes the server represents.ģ.Establish information security by agreeing on encryption mechanisms The SSL session begins with a negotiation between the client and the server as to which cipher suite they will use. The three main purposes of the SSL handshake are to: This exchange of information is called the SSL handshake. In this blog, the connection we want to secure is between WebSphere and a backend Database server.Ĭommunication using SSL begins with an exchange of information between the client (WebSphere) and the server (Database) to negotiate the SSL protocol components. SSL - stands for Secure Sockets Layer and, in short, SSL is the standard technology for keeping an internet connection secure and safeguarding any sensitive data that is being sent between two systems over a network. This blog focuses on SSL connectivity from WebSphere Application Server – JDBC provider and data source configuration with backend database server.
